RATCHET-AND-LEYVER MECHANISM.

SPECIFICATION forming part of Letters Patent No. 375,527, dated December 27, 1887.

Application filed August 20, i887. Serial No. 247,433. (No model.)

To all whom it may concern:

Be it known that I, JOHN BAYET, of OFallon, in the county of St. Clair and State of Illinois, have invented a new and Improved Ratchet-Lever Mechanism, of which the following is a full, clear, and exact description.

The invention consists of a ratchet sleeve or teeth held on the shaft and operated upon by one or more ratchet-levers, and a pawl held in a ring or carrier, through which passes loosely said ratchetsleeve.

The invention also consists of certain parts and details and combinations of the same, as

will be fully described hereinafter, and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding'parts in all the figures.

Figure-1 is a side elevation of my improve ment as applied. Fig. 2 is a side elevation of the same with the front plate of the ring or carrier removed and the pawl disengaged. Fig. 3 is a similar view of the'same, with the pawl engaging the ratchet-sleeve; and Fig. 4 is a plan View of a modified form of my improvement.

The shaft A, of suitable length and diameter, is mounted to rotate in suitable bearings, and carries one or more ratchet-sleeves, B, or

the teeth of the ratchet are directly out on the shaft A. A ratchet lever or pawl, O, is provided with a head, D, which has its bearing in a recess, E, formed in a ring or carrier, F, having a removable front plate, so that said head of the lever O can easily be placed into said recess E. On the head D of the lever O is formed a. semicircular projection, G, which is the fulcrum of said lever, and on said head is also'formed a jaw, I-I, adapted to engage 0r disengage the teeth of the ratchet-sleeve B.

It will be seen that the motion of the ratchetlever O is limited by the peculiar shape of the recess E, usually to the distance of one or two teeth of the ratchet-sleeve B. It will further be seen that when the leverGis moved upward in the direction of the arrow at, as illustrated in Fig. 2, the said lever swings on its fulcrum G, so that the jaw II disengages the teeth of the ratchet-sleeve B, whereby the wheel F is turned by the lever G, and the ratchet-sleeve B and its shaft A remain stationary. When the ratchet-lever G is moved downward in the direction of the arrow 1), as illustrated in Fig. 3, then the jaw H engages one of the ratchetteeth, thus turning the ratchetsleeve B and the shaft A. The motion of the latter can be transmitted in any suitable manner to other machinery.

Any number of ratchet-sleeves and corresponding levers can be secured to one shaft,or to several shafts coupled together, and the free ends of said ratchet-levers O can be connected by links I with crank-arms J, secured to a shaft, K, having a rotary motion, so that when the said shaft K is rotated said links I impart a swinging motion to the said lever O,

, so thata continuous rotary motion isimparted to the shaft A, as illustrated in Fig. 1.

Instead ofusing one ratchet-lever, G, for

each ratchet-sleeve B, I may fork the lever O,

as illustrated in Fig. 4, and provide each end of the fork with a head, D, operating in the ring or carrier F and on the ratchet-sleeve B.

It will be seen that with my improved ratchetTIeVer mechanism I am enabled to impart a partial rotary motion or acontinuous rotary motion to the shaft, increasing at the same time the power of the latter. VVhenseveral ratchet-sleeves and corresponding levers are placed upon one shaft, each lever may be operated independently of the others. The number of levers and ratchet-sleeves can be varied according to the work to be done, and the length of the levers is determined according to the space in which they are to be used or the amount of power they have to communicate.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the shaft and the ratchet,of the ring or carrier F,having an opening, E, anda curved recess in one wall thereof, of the lever 0r pawl G, extending through said opening, and formed on its inner end with a semicircular projection, G, fitting in said JOHN BAYET.
